IMPROVEMENT IN BENCH-KNIVES.

Specifieation forning part of Letters Patent No. %14,494, dated April 2 1879 application filed January 18, 1879.

To all whom it may concm:

Be it known that I, GEORGE S. DERE, of the city of New Orleans, parish of Orleans, and State of Louisiana, have invented a new and useful Improvement in Bench-Knives, of which the following is a specification. V

The bench-knife is used for the purpose of holding Wood material firnily upon the Workbench while it is being dressed. v

Heretofore a. knife has been in use that has been broken from the blade of a case-knife, or constructed in such a manner as to endan ger the m ateri al by splittin g it, defaeing the planes, or nicking the plane-hits.

The object of my invention is to provide a 4 knife that does not split the materia-l orinjure the tools' while working it.

The invention consists of an oblong steel or case-hardened iron plate, toothed and beveled at the front end, and halt' square and half beveled at the butt, from the under surface ot' which projects a triangular knife, to be constructed of difi'erent sizes, so that it can be applied to any Wood material.

In the accoxnpanying drawings, in which similar letters indicate like parts, Figure l shows the top, and Fig. 2 the under, surface of the bench-knife.

' Letter A is the oblong plate, having the front end, B, toothed and beveled, so thatitca-n be driven slightly into the material, and the butt G half square and half beveled, so that it can be struck With the face of 'or forced up from the work-bench with the claw of a hammer. D is the triangular knife proiiecting from the under surface of the oblong plate A, and is driven into the Work-heheh when the bench-knife is in use.

What I claim is The bench-knife described, consistin g of the upper portion, A, made sharp, and having teeth at its front end, and having the sharpened triangular blade D projectiug at right angles therefrom, :s shown and described.
